exciton binding energy meaning in Chinese
激子的结合能
Examples
- Zinc oxide ( zno ) is a wide band - gap semiconductor , 3 . 37 ev at room temperature , with the high exciton binding energy of 60 mev
Zno是一种宽带隙半导体材料,室温下它的能隙宽度为3 . 37ev ,激子束缚能高达60mev 。 - Using a simple variation - fitting method ， the exciton binding energies of a sawtooth - shaped quantum well are calculated as a function of an electric field ， and the explanation of the results is also given
采用一种变分拟合的简单方法计算了电场下锯齿型多量子阱的激子结合能，对计算结果给出了合理的解释 - Dongxu zhao ( condensed matter physics ) directed by prof . dezhen shen and prof . yichun liu zinc oxide ( zno ) is a wide band - gap semiconductor ( 3 . 37 ev at room temperature ) with the high exciton binding energy of 60 mev
<中文摘要> = zno是一种宽带隙的半导体材料，室温下它的能隙宽度为3 . 37ev ，激子束缚能高达60mev 。 - In low - dimension structure , the exciton binding energy will be lager than bulk material because of quantum effects , so excitons play an important role in optical characteristics of low - dimension zno
在低维结构中，由于量子限制效应，激子束缚能会变得更大，因而在低维zno材料中，激子发光在其光学特性中起着举足轻重的作用。 - Due to the large exciton binding energy of 60mev , which ensures the high efficient excitonic emission at room temperature , it is regarded as one of the most promising materials for fabricating efficient ultraviolet ( uv ) and blue light emitting devices
由于氧化锌具有较高的激子束缚能( 60mev ) ，保证了其在室温下较强的激子发光，因而被认为是制作紫外半导体激光器的合适材料。
